What Other Fish To Add?

[x-Twinkle-x]

I have a small 70L, heavily planted, that atm has my male crowntail betta, 3 platies (2 female, 1 male) 1 albino ADF & 1 dojo loach. All fish are fine together, my betta can sometimes be a bit possessive over his food but other than that is fine, he gets on especially well with my ADF
Is there enough room to add a few more fish? I was thinking maybe 3 swordtails, but I have never kept them and not sure of how they would be with my betta. He is generally quite laid-back, and has been fine with all of the other fish that he has come across. Obviously I can't have guppies because of the betta, and I'm not sure what tetras I could have. I think danios would be too fast for the betta's liking, and would they nip his fins??
I only want a few more fish, as the tank is quite peaceful and simple and that's how I like it lol. In one of my other larger tanks, I have an odd purple emperor tetra that got mixed up in the bag when I got my scissortail rasboras. Instead, could I move him to my 70L and buy maybe 5 more of them? How would they be with the others?

Thanks in advance

EDIT: Forgot to add that I would like some sort of small algae eater, I was thinking corys but not sure... any ideas?

Maybe a little shoal of ottos? good little algae eaters and so funny to watch

i think dojo loaches prefer to be in groups so that would be good, cories don't eat algae but are a active addition to any tank

Thanks everyone! I bought 4 swordtails and also accidentally ended up with a sailfin molly but I am still after a small plec that will eat algae. Not that I actually have any algae yet lol but obv I will feed catfish pellets.
I was thinking about bristlenose, but how many could I get with over-stocking the tank?

Thanks

Dojo's can also get aggressive and IMO get too big and active for an aquarium that size. Bristlenoses are fine for that size aquariumm though if you don't have an algae problem or even if you do, they won't do much to stop it. They also need some fresh vegetable and the occasional worms or insect larvae in their diet too.

In short, if you don't have algae, you don't need an algae eater and if you do have algae, an algae eater isn't going to get rid of it all. Better to use a brush or algae sponge to remove it.

My plecs are good at getting some of the larger patches but still need a little "assistance" to get rid of the rest.
